Is it normal to hear banging while supercharging?

[classychris92]

I went to a supercharger for the first time and I heard 2-3 bangs coming from the undercarriage and felt like it was under my drivers side. I only added 20% to get me home so those bangs were in between then. Is this something I should bring it in for or is this part of supercharging? I did precondition but was only 8 minutes from the SC so maybe that was the problem? (2018 M3 LR)

Normal. In colder weather it happens more, but it’s a normal part of supercharging probably due to the increased power and temperature over home and most destination charging.

Totally normal, in colder temps also you could even see smoke coming from the car which is condensation

temperature differences, dilation, and battery vents. As others say, normal and happens more in cold weather since there's a bigger temperature change in the battery.

My car did this for the first year, apparently due to sheet metal "popping" as it flexed due to the temperature change.

you'll also hear that banging going up and down hills too

Highly inappropriate. Get a room, people!

Thank you and everyone else who knew this lol. I'm not gonna lie it had me a bit worried. Especially since when I went to make this post I checked the discussions that come up and didn't see anything about this so I thought it was a unique problem lol. I do have another question. My little brother has a 2021 M3P and he has the option to turn on both seat heaters from the bar at the bottom of the screen. Mine doesn't give me that option. I assumed even tho mines older we'd have the same software. Is there something I need to do?

I think you have to long-press one of the bottom bar buttons in order to customize which ones are display (if I remember correctly).

This is a weird sound. You may had experienced it in the past.

Mine went from the did something explode under the car thunk, to just a normal thunk after this was done.

Yeah I did. You can see it in the picture. There front defrost, rear defrost, left seat heater. And that's it. So annoying idk why it wouldn't be there. Obviously not something I wanna bring it to Tesla for but I just dk how to fix it @GtiMart do you have any ideas how to fix it?

Only if you’re supercharging next to a Model Y or 3. The better sound deadening in the S and X will make sure you won’t hear the naughtiness going on next to you.

The passenger seat only appears on the display when you have a passenger.

I’m guessing it was just you in your car.

On my 2018 M3P, I heard about a replacement battery compartment "vent" that could be installed to replace the original vents that minimized the sound of the "bang" when Supercharging. I requested the service and it was performed rather quickly at the Service Center at no cost. It did seem to make the noise much less noticeable, although I still hear a bang periodically, but it's significantly less pronounced. You might want to see if this is still available.

Really?! How long ago did you do it? Was it under warranty and that's why it was free? Cause mines not under warranty anymore but I'm super interested

What's funny is before i asked I read a discussion that said this same thing. But the poster said "no even with someone in the seat doesn't come up" so I assumed it be the same for me. But you are absolutely correct lol. My OCDish would still prefer it to be there always, I like uniformity

Not just that, but when the passenger gets out and that icons goes away, it hides the state of that seat heater (but doesn't shut it off). Likely making it very common for people to have their passenger seat heater left on with no one sitting there.

It didn't used to be that way... that came in v11 software. The previous software (v10), in my opinion, was better and more closely followed the "principle of least astonishment".

Well don't call Tesla Customer support.

All they will suggest is a double scroll wheel reset. lol.

Yeah I really would of rathered it just stay lol. Do you ever feel you seats getting hot even when they are off? Cause it keeps happening to me
